Komi Can't Communicate, Vol. 28 (manga)

Now that Komi and Tadano are an official couple, Komi’s dad wants another chance to bond with his daughter’s boyfriend, this time on a sauna date! It’s just as awkward as it sounds, but Tadano manages to make things even more cringe when a heat-induced delirium prompts him to ask Komi’s dad the worst question in the history of questions - how do you kiss a girl?
